Pehea e hana ʻia ai ke ʻano o ka hana ʻana i ka waikawa propionic mai ka huahana ʻaoʻao o ka waikawa acetic?
ʻAkika Propionic ua hana mua ʻia ma o ka fermentation o ke kō a i ʻole ka starch, a i ʻole ma o ka hoʻokaʻawale ʻana i ka wā o ka carbonization lāʻau a i ʻole ka distillation maloʻo. Eia nō naʻe, he ala paʻakikī ka fermentation no ka hana ʻana o ka propionic acid. Ua kāohi ʻia ka hana ʻana o ka propionibacteria o ka propionic acid e nā huahana hope, e paʻakikī ai ka hōʻiliʻili ʻana i nā ʻano kiʻekiʻe o ka huahana. Eia kekahi, he paʻakikī ka hoʻokaʻawale ʻana o ka huahana, e hoʻolilo ana i nā ʻano fermentation i mea hoʻokūkū ʻole i hoʻohālikelike ʻia me ka synthesis kemika.
ʻO ka oxidation pololei o nā hydrocarbons kahi ʻano hana mua no ka hana ʻana i ka waikawa acetic. Ma ka hoʻohana ʻana i ka naphtha māmā, ke kinoea petroleum i hoʻoheheʻe ʻia, a i ʻole nā alkanes me nā kiko paila ma lalo o kahi mahana e like me nā mea maka, a me nā manganese, cobalt, a i ʻole vanadium oxides e like me nā mea hoʻoulu, hana ʻia ka oxidation ea wai-phase ma 150-250 ° C a me 1.0-5.0 MPa e hana i ka waikawa acetic, me nā huahana ʻaoʻao e like me ka waikawa formic a me ka waikawa propionic. No kēlā me kēia tona o ka hydrocarbon māmā, 0.65 tons o ka waikawa acetic, 0.06 tons o ka waikawa formic, a me 0.05 tons o ka waikawa propionic hiki ke hana ʻia. Hoʻohana kēia kaʻina hana i nā mea maka haʻahaʻa haʻahaʻa a he kaʻina hana maʻalahi, akā ʻo ka hoʻohuihui paʻakikī o ka hui hopena e pono ai ka distillation extractive a me ka distillation azeotropic no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana, e hopena ana i nā kumukūʻai hoʻopukapuka kālā kiʻekiʻe.
